Electrochromic system

摘要

An electrochromic system. It comprises layers of solid/materials deposited on glass or another substrate. The solids function in an atmosphere that can be dry. One layer is preferably Li3AlF6 and conducts positive lithium ions. Another layer is a counterelectrode. The counterelectrode is improved to the extent that it can reversibly accept ions from and donate them to the ion conductor while remaining extensively transparent. The counterelectrode can be LixTiOy, (Li2O)m(WO3)n(Sb2O3), or (Li2O)m(WO3)n(CeO2)o.
